BALlNG-PRESS.

SPECIFICATION forming part of Letters Patent No. 412,167, dated October 1, 1889.

Application filed March 1, 1889. Serial No. 301,689. (No model.)

To all whom it may concern.-

Be it known that I, J OSEPH DISMAN, a citizen of the United States, residing atDayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Bailing-Presses and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, ref erence being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

Myinvention relates to improvements in baling-presses, the several features of which will be fully hereinafter set forth.

My press has two compression-chambers in opposite ends of the frame, and the compound plunger operates alternately, so that when one end is being charged with hay the hay in the other is being compressed. The requisite movement is given by an endless chain, which has a continuous movement in one direction, and by engaging projecting plates on the plunger-rails a reciprocating motion is given to said plunger.

The mechanism is illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of the haypress, the left-hand end being in central longitudinal section, and a portion of the same broken out, and the greater part of the central portion being also shown in section, the plane of the section being parallel to the central section and nearer the front side of the press. Fig. 2 is a transverse section of the same on line a: 0;, Fig. 1. Fig. 3is asprocketwheel with one link of a chain. Fig. 4 is a link of an endless chain with lateral projections.

Like letters designate like parts throughout the several views.

A is the frame, which is not materially different from those in use. The end pieces D serve to close the ends,'and are firmly held in position by any suitable appliance. The compression-chambers in the ends of the frame occupy a space less than one-third of the length of the frame. Near the inner ends of the compression-chambers are the hoppers B, through which the hay is fed to the said chambers. The compound plunger comprises two heads 0 and O, firmly united by the two rails K K. The rails may be attached to the heads by the angle-iron 'n, or by any other means by which the several parts can be rigidly held together. To the upper and lower rails are firmly bolted the projecting plates m, the inner ends of which extend over the side of the endless chain,

and therefore engage the projecting lug J of the link. Vtithin bearings in the uprights O O are held the shafts of the sprocketwheels F F, and on these wheels is carried the sprocket-chain E, to one link of which are attached the lugs J, one on each side of the said I sprocket-chain, and which engage the four projecting plates m m of the rails, and, thereby, as the chain is carried along, a reciprocating movement is given to the plunger, one serving to carry the plunger in one direction and the other in the opposite direction. The ordinary form of end less chain will answer the purpose; but 1 prefer a wheel and chain, as illustrated in Figs. 3 ands,

The sprocket-wheel F has six concavities on its periphery to engage the convex surfaces of the chain, and has central lugs that enter cavities of the links to prevent the chain leaving the wheels.

At Fig. 4: is shown the top of the link I, the sides terminating at the dotted lines y y, and the projections J J beyond the link proper are the projecting plates that engage the lugs bolted to the sides of the rails of the compound plunger.

H, Fig.2, is the driving-pulley;G, the shaft, and L the sprocket-wheel.

The operation is thus: Power is applied to the driving-pulley. This causes the chain to carry the compound plunger in one direction to compress the hay in one chamber, and as this is being done hay is placed in the opposite chamber. The chain in its movement is detached from the projecting plates on one side and, traversing about one-half of a circle, engages the projecting plates on the opposite rail, and the movement is reversed,

thus alternately compressing the hay in the chambers.

lhe machine would be effective if one of the chambers was dispensed with.

Having fully described my invention, What I claim, and desire to secure by Letters Pat-- cut, is

1. The combination, with the press-frame having a compression-chamber at each end, of the sprocket-wheels journaled in said frame, the endless sprocket-chain carried by said Wheels and havinga laterally-projecting lug, the plunger-heads, the rails connecting the same, and a projecting plate on each of said rails, so arranged as to be engaged alternately by the lug on the sprocket-chain to reciprocate the plunger-heads and their connecting-rails, substantially as described.

my own I affix my signature in presence of 30 two Witnesses.

' JOSEPH DISMAN.
